Frequently Asked Questions    
What is a Fireplace damper?
A fireplace damper, usually located in the throat of a masonry chimney just above the firebox, is a device that is meant to seal your fireplace shut when it is not in use. This is necessary so that heated air from your home will not escape up the chimney when the fireplace is not being used. An open or leaky damper can add hundreds of dollars a year to your heating costs.

Why do most fireplace dampers leak?
Most fireplace dampers form a metal to metal seal which even when new allows air to leak through. Over time, as the metal plates warp due to the effects of heat and moisture, the seal worsens and more and more warm air escapes up the chimney even when the damper is closed.

What makes a Lyemance damper a great energy saving alternative to your original fireplace damper?
The Lyemance, Top Sealing damper seals with a silicone rubber gasket. When you close our damper warm air is sealed in and cold air is sealed out. This tight sealing gasket means that our damper will reduce unwanted heat loss by 90%. And, unlike replacement throat dampers, the Lyemance Dampers has a lifetime warranty.
